Schottky Rectifier, 15 A
12TQ...S
Vishay High Power Products
FEATURES
• 150 °C TJ operation
• Very low forward voltage drop
• High frequency operation
• High purity, high temperature epoxy encapsulation for
enhanced mechanical strength and moisture resistance
• Guard ring for enhanced ruggedness and long term
reliability
• Designed and qualified for Q101 level
DESCRIPTION
The 12TQ...S Schottky rectifier series has been optimized for
very low forward voltage drop, with moderate leakage. The
proprietary barrier technology allows for reliable operation up
to 150 °C junction temperature. Typical applications are in
switching power supplies, converters, freewheeling diodes,
and reverse battery protection.
